BED OR4 MATTRESS SUPPORTING FRME.

SPECIFICATION forming part of Letters Patent No.'251,630, dated December2*?, 1881.

Application tiled J" une 20, 1881'. (No model.)

, To all whom it may concern:

Be it known that I, FREDERIC A. PALMER, a citizen of the United States,and a resident of the city, county, and State of New York, have inventeda new andA Improved Bed or Mattress Supporting Frame; and I do herebydeclare that the following is a full, clear, and exact descriptionthereof, reference being had to the accompanying drawings and letters ofreference marked thereon, forming a part of v this specification, inwhich drawings- Figure 1 is a plan view of my improved supporting-framefor beds or mattresses. Fig. 2 is a side elevation of the same, and Fig.3 is a sectional view of a portion of the supportingframe in theline x.fr of Fig.1.

The main object of my invention is to provide a bed-bottom orsupporting-frame for beds and mattresses, whereby, when its side railsare set between the side rails of a bedstead, the end rails of thesupporting-frame will afford the means for. holding the frame inposition upon the bedstead without other appliances for lsuch purpose,while at the same time the end rails of said frame will afford a supportwhereby the elastic fabric stretched over the frame may be extended outbeyond the side rails of the bedstead, so that a person sitting upon aside edge of the fabric will not have his body come in contact with orpress upon a side rail of the bedstead.

In the drawings, A Aare the end rails, and B B the side rails, of myimproved bed-bottom or supporting-frame for beds and mattresses. The endrails, A A', are secured in position upon and at the ends of the siderails, B B, as shown, and are of such thickness that when the woven-wirefabric or other fabric, as at C, is secured upon the upper surface ofthe rails A A', as indicated in the gures, said fabric will not only beelevated a considerable distance above the side rails, B B, as indicatedin Fig. 2, but will also extend out laterally beyond and above said siderails, as representedin Fig. 1. 'Ihe fabric C is confined in positionupon and over the end rails by having its ends confined between therails A A and abutting strips d d, as indicated, said strips beingbolted to the rails A A' in any proper manner, so as to prevent the endsof the fabric G from being drawn out from between the strips el d andrails A A' when the fabric is under longitudinal strain. The fabric C,it will be seen, is practically of a width equal to the length of theend rails, A A', and these end rails are of such length that when mybed-bottom or supporting-framefor beds and mattressesis in use the endsof the rails A A and the sides c 0 of the fabric C will extend so farbeyond and above the side rails of the bedstead that a person sittingupon one ot' the sides cof the fabric will not be subjected to thediscomfort of having the fabric pressed down by his weight upon a siderail of the bedstead.

The end rail A', I confine immovably iu place upon the side rails,B,bybolts b, or in any other proper manner. The end rail A, I make adjnstable on the rails late the tension of the fabric Gand keep it leveland taut. This I eEect by confining the rail A to the side rails, B B,by means of bolts b', which pass through a slot, e', in a rail-plate, E,which is seated in the side rails, as shown, and confined thereto by abolt, G, which at its upper end is flaring and tits in a daring socketin the rail-plate, and at its bottom is held in position by a screw-nut,g2, thereby confining the end rail A to the rails B B. This railplate E,as shown in Fig. 3, has a screw-bolt projection, e, through which ascrew-bolt, F, passes, and which bolt has its inner end rounded to fitinto a corresponding cavity in a bearing-washer, f, which abuts againstthe inner surface of the rail A, as shown. Beneath the plate E the railB is cutaway, as shown atv e2, so that when the screw-bolt F is screwedup and the rail A forced outward, in order to tighten the fabric C, thenut b2 and lower end of the bolt b will travel in e, while an upperportion of the bolt is free to travel in the slot or opening e of theplate E during the outward movement of the rail A. By this means mysupporting-frame for beds and mattresses is provided with a permanentfixture, ready for operation whenever it is desirable to tighten thewoven-wire or other suitable fabric, C, and keep it level and taut, andupon which fabric a bed or mattress is laid when in use.

I claim- 1. A bed-bottom or supportingframe for beds and mattresses,which comprises in its construction end rails, A A', which project be- BB, in order to regu-l IOO `yond its side rails, B B, and kel. woven-Wireor b', Vpassing.througlil the rail and the slot e in I other suitablefabric, C, whiehextends laterthe ,plate E, substantially as and for thepurally outward beyond and above the side rails, pose described.
